Today I was at Petland and I bought a female platy. (I forgot what type of platy it is!!) Apparently Skyler (my betta) turned out to be sick. so i put him in a 1/2 gallon tank i had and cleaned out my 10 gal completely. It was really filthy under the gravel Then After all that i put my platy in. Skylar is still in the other tank with medication but after he gets better will he be okay with the female platy? or should i get a few more platys? Will that be okay? please answer.

I think you should have at least 3 Platies. It depends on his personality, though. It's never certain whether or not a Betta will get along with other fish. You may end up needing to buy him his own tank if they don't get along.

A picture would help, but I doubt it's a tetra. You can rarely tell the difference between a male and a female. Find a picture on Google Images and post it here. I'll tell you what it is and if it's compatible with a Betta, okay?
